The paper describes an advanced, integrated approach to structural modelling, design and analysis of underwater vehicles, employing methods ranging from simple formula-based design tools to 3D geometric modelling and non-linear finite element analysis. Emphasis is given to a specially developed domain-specific language called RMGScript for creating 3D structural geometric entities within a hierarchical and relational framework, as well as capabilities uniquely oriented to structural modelling of underwater vehicles, such as incorporating out-of-circularity imperfections in pressure hull geometry, and representing localised variations in plating thickness using thickness zones or maps. Applications to structural modelling of a submarine are illustrated throughout the paper. It concludes with example results for a notional submarine exhibiting pressure hull strength prediction, global and local stress analysis, and dynamic analysis.
